-Another common use case is to proxy certain requests to different servers (e.g. you'd like to use data from a different environment). For example, the following command would proxy `http://127.0.0.1:8000/api/users/1` to `https://internal-service.local/api/users/1`:
+Another common use case is to **proxy certain requests to remote servers** (e.g. you'd like to use data from a different environment). For example, the following command would proxy `http://127.0.0.1:8000/api/users/1` to `https://internal-service.local/api/users/1`:
 
 ```sh
 $ ws --rewrite '/api/* -> https://internal-service.local/api/$1`
 Serving at http://mbp.local:8000, http://127.0.0.1:8000, http://192.168.0.100:8000
 ```
 
+Imagine the network is down or you're working offline, proxied requests to `https://internal-service.local/api/users/1` would fail. In this case, you could use Mock Responses to fill the gap. Define the mock responses in a module.

 ## Advanced Usage
 
 Being modular and extensible, features can be added or removed from `ws` in the shape of Middleware, ServerFactory or View modules. [See the wiki for full documentation and tutorials](https://github.com/lwsjs/local-web-server/wiki).
